Embodiment Construction
[0034] figure 1 An embodiment of the valve is shown with a valve housing 2 defining an inlet opening 4 and an outlet opening 6 . A spacer 8 is provided in the valve housing 2 and defines a bore in which the valve insert 10 is sealingly mounted.
[0035] The valve insert 10 has a valve insert housing 12 in which a spindle 14 is rotatably supported, the spindle 14 being supported by means of an adjustment top 16 which is screw-fastened to the valve insert housing 12 . The adjustment top 16 has a protrusion that engages over a portion of the main shaft 14 to axially fix the main shaft 14 in place relative to the valve top 16 . The valve top 16 is screw-fastened inside the valve insert housing 12 and can be adjusted there, allowing the spindle 14 to be preset.
[0036] The spindle 14 is a non-rising spindle which engages a setting element 18 which on the opposite side cooperates with a valve disc 20 which engages the opening of the setting element 18 by means of a cam. On the ...

The present invention relates to a valve for drinking water installation, comprising a valve housing (2) with connections to a pipeline, and a regulating piston (28), which is movable in the valve housing (2) and coupled to a spindle (14) exposed on the outer side of the valve housing (2) and which cooperates, on the side opposed to the spindle (14), with a thermal expansion element (24) exposed in a flow path through the valve housing (2) and resting under the pretension of a spring element (34) against the regulating piston (28), the regulating piston (28) being movable relative to a bore (54) due to the expansion of the expansion element (24). For providing an insofar im-proved valve for drinking water installation which, depending on an adjustable or non-adjustable temperature, allowsa larger volume flow of cold water, if a water temperature is higher than this temperature, and which, in the case of a low temperature, preferably controls the flow rate to a minimum volume flow, thepresent invention proposes that the regulating piston (28) defines a Kv min setting area (I), through which, at the Kv min position of the regulating piston (28), a Kv min flow passage (56) is formedbetween the regulating piston (28) and the bore (54) by at least one circumferentially non-continuous gap (58, 60) extending radially on the regulating piston (28) and / or the bore (54) and / or that the regulating piston (28) defines a Kv max setting area (III) with support points (62) formed on the outer circumferential surface of the regulating piston and intermediate flow passage hollows (64), and that, at the Kv max position of the regulating piston (28), the support points (62) extend up to the bore (54) and the flow passage hollows (64) provided therebetween define a Kv max flow passage (III).
Description
technical field [0001] The invention relates to a valve for a drinking water installation according to the features of the preamble of claim 1 . Such a valve is known from DE 10 2011 010 840 A1. Background technique [0002] The invention relates in particular to valves for regulating cold water circulation. A flow path for drinking water is formed in the valve housing, in which flow path a thermal expansion element is exposed, which rests against the adjusting piston under the pretension of the spring element. Due to the expansion of the expansion element, the adjustment piston moves relative to the bore. As a result, a temperature-controlled regulation of the flow through the valve is performed. The purpose of this flow through the valve is to set a Kv minimum for cold drinking water so that only minimal circulation will occur when the drinking water is cold enough. On the other hand, if the temperature of the potable water increases, the purpose of increasing the circ...
